Hertel K027784AS Straight Flute Tap M16 X 1.50 Metric Fine

Product Description

The HERTEL K027784AS is a straight flute tap designed for cutting Metric Fine internal threads in a range of ferrous and non-ferrous workpiece materials. This tap carries an M16 x 1.50 thread designation and features a taper chamfer that gradually engages the workpiece, making it well suited for through-hole threading applications where the lead-in can extend across several threads. Manufactured from high speed steel with a bright, uncoated finish, the K027784AS delivers solid performance in general-purpose machine tapping and hand tapping operations. With 4 flutes and a D6 thread limit, it holds tolerance for standard metric fastener fits. Overall length is 3-13/16 inches and the unit weight is 1.15 pounds.

This tap is used in production machining, maintenance and repair, and toolroom environments where Metric Fine thread forms are required. Metric Fine threads are common in applications demanding higher thread engagement strength or finer pitch adjustment than Metric Coarse, including automotive, hydraulic component, and precision mechanical assembly work. The taper chamfer style makes this tap a practical choice when starting alignment and gradual thread engagement are priorities. A licensed machinist or qualified toolroom technician would typically install this tap in a tapping head, CNC machining center, or manual drill press with appropriate tapping fluid.

Key Features

• M16 x 1.50 Metric Fine thread form for precision thread engagement
• Taper chamfer for gradual lead-in and easier thread starting in through holes
• 4 straight flutes for chip clearance in moderate-depth tapping operations
• D6 thread limit for standard metric tolerance fits
• High speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for use with standard tapping fluids

Compatibility

Designed as a standard straight flute tap for general Metric Fine M16 x 1.50 through-hole threading applications in machine or hand tapping setups.

Installation Notes

This tap should be installed by a qualified machinist or toolroom technician familiar with tapping speed selection, appropriate cutting fluids, and workpiece fixturing. Always secure the workpiece firmly before beginning the tapping operation, and ensure spindle alignment to prevent tap breakage. Use a suitable tapping fluid or cutting oil for the workpiece material. Follow applicable shop safety procedures and machine guarding requirements during operation.
